Solomon Grundy (by Imaginext), Found on a Monday (at Target).
Hall of Doom, and there are only four Superfriends Legion of Doom characters yet to make it to the Imaginext line: Giganta, Toyman, Sinestro and Cheetah. Here's hoping we get them all - and that Giganta is also released as a big-fig!
Robin's Mech Suit makes for great GrundyBuster Iron-Robin play scenarios! Take THAT Age of Ultron!
